Fig 2 (A) Selective angiography with contrast filling of a large collateral from the aortic (Ao) arch serving the right middle and inferior lobes. (B) Computed tomography (CT) angiography maximum intensity projection coronal image showing the distribution toward the right pulmonary hilum with multiple side branches. (C) Three-dimensional volume-rendering “cut-plane” image showing the arterial collateral branches from the subclavian artery (white arrow) and the aortic arch (black arrow). (D) Selective injection with contrast filling of a large collateral from the thoracic aorta to the left lung. The coil occluding the collateral from right subclavian artery (RSA) (A and B) and the plug occluding the collateral from the aortic arch are shown (B). CT images: volumetric prospective electrocardiographically gated (40% R-R interval) CT acquisition with a 320-row CT scanner (Toshiba Aquilion One, Toshiba Medical System, Tochigi-ken, Japan) with intravenous administration of iodinated contrast by the antecubital vein.
